2 MEASurement Commands
READ[1]|2|3|4[:SCALar][:POWer:AC]:RELative?
[<expected_value>[,<resolution>[,<source list>]]]
This command sets the specified window's measurement function to single
channel with relative mode on, aborts then initiates the specified channel,
calculates the measurement result and places the result on the bus. The result is a
ratio based measurement and is expressed in the units defined by
UNIT[1]|2|3|4:POWer:RATio. The relative value used is that set by the
CALCulate:RELative:MAGNitude:AUTO command.
INITiate:CONTinuous must be set to OFF, otherwise error –213, "INIT ignored"
NOTE
occurs. If TRIGger:SOURce is set to BUS, error –214, "Trigger deadlock" occurs.
